摘要水库蓝藻优势的生态过程与湖泊、河流蓝藻优势的生态过程不同。为探讨大型水库运行对蓝藻的影响，2007 ~ 2009年在三峡库区典型支流彭溪河回水区进行了为期2年的蓝藻监测。根据水库的季节性调度，将数据分为3个子集。枯水运行期间，由于温度分层，强降雨将悬浮物和营养盐带入彭溪河回水区。与高水位运行期和水库泄水期相比，这些驱动因素导致水体中总颗粒物水平相对较高，真光层深度水平较低。在这两个时期，水温的升高刺激了大多数蓝藻的生长。结果表明，大规模运行导致了彭溪河回水区生境结构的不同，与水深、水库容积和营养盐动态有关。这些影响密切相关的季节性效应，如降雨量，河流流量和水温，这导致在水库运行阶段之间的栖息地的差异。
Abstract The ecological processes leading to cyanobacterial dominance in reservoirs differ somewhat from those in lakes and rivers. To explore the development of cyanobacteria in response to large-scale reservoir operation, a 2-year, biweekly monitoring program was implemented from 2007 to 2009 in the Pengxi River Backwater Area, a typical tributary of the Yangtze River in the Three Gorges Reservoir. The data were divided into 3 subsets based on the seasonal operations of the reservoir. During the low-water operation period, temperature stratified in the water column, and intensive rainfall brought suspended solids and nutrients into the Pengxi River Backwater Area. These drivers led to relatively high levels of total particulate matter and low levels of euphotic depth in the water column compared with both the high-water operation period and reservoir discharge period. During these 2 periods, increases in water temperature stimulated the growth of most cyanobacteria. We concluded that the large-scale operation caused structurally different habitats in the Pengxi River Backwater Area, related to water depth, reservoir volume, and nutrient dynamics. These impacts were closely linked to seasonal effects, such as rainfall, river flow, and water temperature, which resulted in differences in habitat among reservoir operation stages.
